This red latex rear replacement squeegee blade (#MPVR05918) fits perfectly onto the IPC Eagle CT15B battery, and the CT15E electric line of automatic floor scrubbers. The rear blade is perhaps the most important blade in the whole system. We recommend cleaning it after every use, as it can cause extreme streaking if not taken care of properly. It creates the seal with the front blade, and is responsible for recovering 100% of your floor scrubbing solution, or your floor degreasing solution that you've put down. You should use a degreasing solution for those really heavily soiled floors. You'll also want to make sure to use a defoamer when using a degreasing solution to help protect, and prolong the life of your vacuum motors.
Each squeegee blade (front & rear) can be used on all four sides for recovery of scrubbed solutions. You can use the front side of the squeegee, then rotate, so the back side is facing forward. Then, you can flip it upside down, and use both of those surfaces. No tools are required to switch your blades, and we recommend doing it often. Cleaning each blade after each use (at least wiping them down), will prevent streaking & extend their life expectancy. We recommend rotating your squeegees every 20 hours of scrubbing, so they wear evenly and last longer.
